    • The present invention relates to the crystalline, polymorphic Form X of the calcimimetic compound {4-[(1 R , 3 S )-3-(( R )-1 -Naphthalen-1 -yl-ethylamino)-cyclopentyl]-phenoxy}-acetic acid, to methods of preparation thereof, to methods of characterization thereof by single crystal X-Ray crystallography (XRC), X-Ray Powder diffractometry, attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy, Solid State NMR spectroscopy and Differential Scanning Calorimetry (DSC), and to its use. The invention also relates to the preparation of Form X by crystallization from a saturated solution of {4-[(1 R ,3 S )-3-(( R )-1 -Naphthalen-1-yl-ethylamino)-cyclopentyl]-phenoxy}-acetic acid in a C 1 -C 6 alkyl alcohol, or alternatively by precipitation from a neutralized saponification reaction mixture following the alkaline hydrolysis of a C 1 -C 6 alkyl ester of {4-[(1 R ,3 S )-3-(( R )-1-Naphthalen-1-yl-ethylamino)-cyclopentyl]-phenoxy}-acetic acid.
    • 本发明涉及拟钙化合物{4 - [(1R,3S)-3 - ((R)-1-萘-1-基 - 乙基氨基) - 环戊基] - 苯氧基} - 乙酸的晶体多晶型X 酸,其制备方法,通过单晶X射线晶体学(XRC),X射线粉末衍射,衰减全反射傅立叶变换红外(ATR-FTIR)光谱,固体NMR光谱和差示扫描的表征方法 量热法(DSC)及其用途。 本发明还涉及通过从饱和的{4 - [(1R,3S)-3 - ((R)-1-萘-1-基 - 乙基氨基) - 环戊基] - 苯氧基} - 乙酸在C1-C6烷基醇中反应,或者通过碱解水解{4 - [(1R,3S)-3 - ((R) - 1-萘基-1-基 - 乙基氨基) - 环戊基] - 苯氧基} - 乙酸。

    • The present invention relates to the crystalline, polymorphic Form C of the calcimimetic compound {4-[(1 R ,3 S )-3-(( R )-1-Naphthalen-1-yl-ethylamino)-cyclopentyl]-phenoxy}-acetic acid, to methods of preparation thereof, to methods of characterization thereof by single crystal X-Ray crystallography (XRC), X-Ray Powder diffractometry, attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy, Solid State NMR spectroscopy and Differential Scanning Calorimetry (DSC), and to its use. The invention also relates to the preparation of Form C by crystallization from a saturated solution of {4- [(1 R ,3 S )-3-(( R )-1-Naphthalen-1-yl-ethylamino)-cyclopentyl]-phenoxy}-acetic acid in the presence of crystallization seeds of Form C, or alternatively by conversion of an amorphous starting material into the different crystalline polymorphic Form X by crystallization of {4-[(1 R, 3 S )-3-(( R )-1-Naphthalen-1-yl-ethylamino)-cyclopentyl]-phenoxy}- acetic acid, followed by a solid solution transformation thereof into the desired polymorphic Form C.
    • 本发明涉及拟钙化合物{4 - [(1R,3S)-3 - ((R)-1-萘基-1-乙基氨基) - 环戊基] - 苯氧基} - 乙酸的结晶多晶型C 酸,其制备方法,通过单晶X射线晶体学(XRC),X射线粉末衍射,衰减全反射傅立叶变换红外(ATR-FTIR)光谱,固态NMR光谱和差示扫描的表征方法 量热法(DSC)及其用途。 本发明还涉及通过从饱和的{4 - [(1R,3S)-3 - ((R)-1-萘基-1-基 - 乙基氨基) - 环戊基] - 苯氧基} - 乙酸在形式C的结晶晶种存在下,或者通过{4 - [(1R,3S)-3 - ((R)-1)的结晶将无定形原料转化成不同结晶多晶型X 萘-1-基 - 乙基氨基) - 环戊基] - 苯氧基} - 乙酸,然后将其固溶转化为所需的多晶型C.
